Top 15 Seattle-Area Family Activities for August 2026

If you find yourself wondering, “Where has the time gone?” as we head into August, don’t sweat it. There is still plenty of summer left to gather up the crew and make sun-soaked memories before the school bell rings again (my kid’s first day back is Aug. 26!). Fill your warm days and evenings with free concerts, outdoor shows, fairs and fests — and so much play time. Here are my top picks for August’s family activities and events around Greater Seattle.

1. A fixture of summer in Seattle, the Blue Angels’ spectacular airshow and the hydro races are the culmination of Seafair neighborhood events.
